2. Description of the Related Art
Near Field Communication (NFC) is a contactless technology for identification and interconnection. Near Field Communication allows users to exchange the information, access contact and services by using the near electric field magnetic communication (such as the near electric field magnetic communication of 13.56 MHz) between the mobile devices, consumer electronics, PCs or smart electronic devices.
Due to the maturity of the market, the mobile phone with NFC can either support the function of the mobile payment or serve as a point of sale (POS). However, the proximity card reader or other similar elements must be added to the handheld device due to the NFC is operated by sending and receiving magnetic field signalssignal, which will make the size of the handheld device becomes larger, and the layout and the elements of the handheld device might be limited.
A touch link technology of the touch panel device which uses the existing panel and driver IC for communication has been developed recently, and has been described in US 2011/0304583, US 2013/0147760, CN 102916729A. The touch panel device includes a touch sensor. At least a part of the touch sensor includes at least a part of touch panel of the touch panel device. The touch panel can be the touch panel without a display function, such as the touch pad, or with the display function, such as the touch screen. The touch sensor includes the driving electrodes and the sensing electrodes set on the board for forming the capacitor structure. At least one of the driving electrodes and the sensing electrodes is used as the sending electrode, and at least one of the driving electrodes and the sensing electrodes is used as the receiving electrode. Thus, the signal can be sent and received by the existing electrodes and driver IC of the touch panel device so as to achieve the touch linkaccording to the electric field without additional proximity card reader or other similar elements, thus reducing the size and the cost of the touch panel device.

An embodiment of a first touch link electronic device is described, comprising a touch panel and a touch link module. The touch link module is configured to establish a first communication channel to a second touch link electronic device, and receive a permission from the second touch link electronic device via the first communication channel. The permission corresponds to the data shared by the second touch link electronic device to provide the shared data with a property assigned by the permission in the first touch link electronic device.
The present invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
When the sharing device 10 shares data or files to the external receiving device 12, it can firstly configure permission of the data or files to be shared, and then transmit the configured permission and shared data or files with the receiving device 12 through a communication connection. Upon receiving the configured permission and shared data or files, the receiving device 12 can record both received information internally. When the shared data or files are required, the receiving device 12 can make the shared data or files valid only via the configured permission, thereby allowing the shared data or files to acquire safety attributes described by the configured permission.
The configured permission may be data containing a safety permission, with the unreproducible, unsharble, and/or uncaptureable properties, rendering invalid after certain operations, period of time, or interactions of other properties, or a combination thereof. For example, the configured permission may be a Digital Rights Management (DRM) file, a safety file dedicated to Hot Knot technology, or a safety file complying with another touch link technology. The shared data or files may be at least a part of file, video file, text file or executable file, and so on. The invalid data or files after certain operations, a period of time, or interactions of other properties may include the shared data or files becoming invalid after they are used for a period of time, a certain number of times, after an absolute time, or after a certain event is triggered. The triggered event may include a communication disconnection between the sharing device 10 and receiving device 12. For example, when the touch connection L1 and/or wireless connection L2 is disconnected, the shared data or files stored in the receiving device 12 become expired, invalid, or useless. In another example, the shared data will become invalid after 30 seconds after receipt of the receiving device 12.
Moreover, the configured permission may be predefined for different types of receiving devices 12, configured or modified during the sharing device 10 and receiving device 12 performing the touch link operation. For example, when the sharing device 10 identifies that the receiving device 12 is a smartphone, a predefined permission 1 is employed for sharing the data and files, and when the sharing device 10 identifies that the receiving device 12 is a tablet computer, a predefined permission 2 is employed for sharing the data and files. In some embodiments, the configured permission may be predefined for different types of shared data or files. For example, when the shared data or files are image files, the sharing device 10 will utilize permission 3 for sharing the data or files. In another example, a predefined permission is provided on the receiving device 12, the receiving device 12 will determine the permission to be used according to the configured permission from the sharing device 10 and the predefined permission on the receiving device 12, and access the shared data or files by the permission to be used.
The receiving device 12 may invalidate the shared data or files by encrypting the shared data or files so that they become undecodable, partially destroying the shared data or files, deleting the shared data or files or performing any operation which causes the shared data or files to no longer be available for use by the sharing device 12.
The access operations of the shared data or files include opening, playing, displaying, executing, or storing the shared data or files. The receiving device 12 can access the shared data or files. In some embodiments, one sharing device 10 may transmit the same or different data or files and the corresponding configured permission to multiple receiving devices 12. In other embodiments, multiple sharing devices 10 may transmit data or files and the corresponding configured permission to one receiving device 12.
The sharing device 10 includes a permission configuration module 100, a data storage device 110, a touch link module 104, a touch panel 107 and a wireless transmission module 108. The storage device 110 stores permission 105 and data 106. When the sharing device 10 intends to share the data 106 to the receiving device 12, the permission configuration module 100 can configure the permission 105 for the data 106, and then the touch link module 104 can transmit the permission 105 to the receiving device 12 via the touch connection L1, which has already been established between the sharing device 10 and receiving device 12 through a touch in close proximity. In some embodiments, the sharing device 10 and receiving device 12 may exchange safety messages via the touch connection L1 to adopt other wireless communication technology (e.g. WiFi, Bluetooth, and so on) for establishing the wireless connection L2, so that the sharing device 10 can transmit the data 106 to the receiving device 12 through the wireless connection L2. In other embodiments, the sharing device 10 and receiving device 12 may establish the wireless connection L2 directly, so that the wireless transmission module 108 of the sharing device 10 can transmit the data 106 to the receiving device 12. Since the distance between the sharing device 10 and the receiving device 12 is short and may be, for example, 5 mm, therefore transmitting the permission 105 via the touch connection L1 can ensure transmission security. On the other hand, since the bandwidth and/or transmission speed via the wireless connection L2 exceeds that of the touch connection L1, it is used to transmit data 106 with a large data size (in comparison to the permission 105), e.g. a large data size may be anything that exceeds 4 KB.
The receiving device 12 includes a touch link module 120, a storage device 130, a touch panel 127, a permission analysis module 124, a permission control module 126 and a wireless reception module 128. The data storage device 130 is configured to store permission 122 and data 129. When the sharing device 10 shares the data 106 with the receiving device 12, the touch link module 120 can receive the permission 105 and the data 106 via the touch connection L1, which has been established between the sharing device 10 and receiving device 12 through the touch in close proximity, and save the permission 105 as the permission 122 in the storage device 130. Then, the wireless connection L2 can be established between the sharing device 10 and receiving device 12, so that the wireless reception module 128 can receive the data 106 from the sharing device 10 via the wireless connection L2, and save the data 106 as the data 129 in the storage device 130.
In one embodiment, the touch link module 104 includes a sensing module 1042 and a connection module 1044 (not shown). Likewise, the touch link module 120 includes a sensing module 1202 and a connection module 1204 (not shown), wherein the sensing modules 1042 and 1202 have the same structure and functions, and the connection modules 1044 and 1204 have the same structure and functions. The sharing device 10 and receiving device 12 check whether another device is physically nearby (e.g., in close proximity to or touching). In one example, the sensing module 1042 checks whether the sharing device 10 is in close proximity to another device. Upon detecting that another device is nearby, a first communication channel is established via the wireless module 1044. For instance, the sensing module 1042 senses the electromagnetic field between the sharing device 10 and receiving device 12 (e.g., determining the presence of the electromagnetic field through a sending electrode and a receiving electrode on the touch panel, as indicated in
When the receiving device 12 needs to access the data 129 shared by the sharing device 10, the permission analysis module 124 can analyze the permission 122 to identify the validity of accessing the shared data 129. The permission control module 126 is configured to control the access operations of the data 129 based on the analyzed result. When the permission analysis module 124 determines that the shared data 129 is valid, the permission control module 126 can allow the access operations of the shared data 129. Whereas when the permission analysis module 124 determines that the shared data 129 is invalid, the permission control module 126 will forbid the access operations of the shared data 129, and invalidate the shared data 129.
Although
The touch link communication system 1 allows the sharing device 10 to increase shared-data security by configuring permission for protecting shared data.
When the sharing device 10 and receiving device 12 have already established a touch connection L1, and the sharing device 10 is going to share data 106 with the receiving device 12, the sharing device 10 and receiving device 12 start performing the data sharing method 2 (S200). Initially, the sharing device 10 can configure the permission 105 of the shared data 106 according to for example, the type of the receiving device 12, type of the data 106, or user preference (S202). Next, the sharing device 10 can establish the touch connection L1 to the receiving device 12 via a touch in close proximity (S204), and subsequently transmit the permission 105 to the receiving device 12 via the touch link L1 (S206). In response, the receiving device 12 can receive the permission 105 via the touch connection L1 and store it as the permission 122 (S208). The sharing device 10 can then be triggered to establish the new wireless connection L2 to the receiving device 12 using a method that is not the touchlink technology (S210), and subsequently send the shared data 106 to the receiving device 12 via the wireless connection L2 (S212). In response, the receiving device 12 can receive the shared data 106 via the wireless connection L2 and store it as the data 129 (S214). Step S210 is optional, when no wireless connection L2 is established between the sharing device 10 and receiving device 12, the sharing device 10 may transmit the shared data 106 to the receiving device 12 via the touch connection L1, and the receiving device 12 may receive the shared data 106 via the touch connection L1, which is then stored as the data 129 in Step S214. The data sharing method 2 is then completed and exited (S216).
After the data sharing method 2 is completed, the data 129 and the corresponding permission will be available on the receiving device 12. The receiving device 12 adopts the data management method 3 to access the data 129 stored on the receiving device 12 (S300). Firstly, the receiving device 12 can receive an instruction from a user to access the data 129, which includes a command to open, display, play, or execute the data 129 (S302). Upon receiving the instruction, the permission analysis module 124 can analyze the permission 122 and determine the validity of accessing the shared data 129 according to the permission 122 (S304), and subsequently, the permission control module 126 can control the access of the data 129 based on the analyzed permission (S306). For instance, when the permission analysis module 124 determines that the access of the shared data 129 has exceeded the number of times or period of time for accessing the data 129, it will invalidate the access operation of the shared data 129. Consequently, the permission control module 126 is not allowed to access the shared data 129, and invalidate the shared data 129. When the permission analysis module 124 determines that the access of the shared data 129 has not yet exceeded the number of times or period of time for accessing the data 129, it will grant the access operation of the shared data 129. Consequently, the permission control module 126 is allowed to access the shared data 129. The data management method 3 is then completed and exited.
When determining to share the data 106, the sharing device 10 starts performing the data management method 4 (S400). Firstly, the permission configuration module 100 configures a permission 105 of the shared data 106 according to what type of the receiving device 12 is being used, type of data 106, or user preference (S402). The permission 105 may indicate the validity of the shared data 106. For example, the permission 105 indicates that the shared data or files 106 is invalid after certain operations, a period of time, or interactions of other properties, including the shared data or files becomes invalid after using the shared data or files for a period of time, for a number of times, after an absolute time, or after certain event is triggered, wherein the event may be the touch connection L1 and/or wireless connection L2 is disconnected. The permission 105 may also indicate the access property of the shared data. For example, the permission 105 may indicate security information, having the unreproducible, unsharble, and/or uncaptureable properties.
Having the touch link L1 established between the sharing device 10 and receiving device 12, the touch link module 104 can deliver the permission 105 to the receiving device 12 via the touch link L1 (S404). Next, the sharing device 10 and receiving device 12 can establish a new wireless connection L2 triggered by the wireless transmission module 108 (S406), and the wireless transmission module 108 of the sharing device 10 may transmit the shared data 106 to the receiving device 12 via the wireless connection L2 (S408). After transferring the data 106 and corresponding permission to the receiving device 12, the data management method 4 is completed and exited (S410).
When the sharing device 10 and receiving device 12 have already established the touch connection L1, and the receiving device 12 determines to access the data 106 from the sharing device 10, the receiving device 12 starts performing the data sharing method 5 (S500). Firstly, the touch connection module 120 of the receiving device 12 can receive the permission 105 (first permission) of the shared data 106 via the touch connection L1, which is saved as the permission 122 in the local data storage device. Later, the wireless reception module 128 of the receiving device 12 can establish a wireless connection L2 to the sharing device 10 (S504) and receive the shared data 106 via the wireless connection L2 (S506), which is saved as the data 129 in the local data storage device. Once the receiving device 12 obtains an instruction from a user about accessing the data 129, the permission analysis module 124 can analyze the permission 122 and determine the validity of accessing the shared data 129 according to the analyzed permission 122 (S508), and subsequently, the permission control module 126 can control access to the data 129 on the receiving device 12 based on the analyzed permission (S510). For instance, when the permission analysis module 124 determines that the shared data 129 has been accessed more than a certain number of times, or for longer than the allowable period of time for accessing the data 129, it will invalidate the access operation of the shared data 129. Consequently, the permission control module 126 is not allowed to access the shared data 129, and invalidate the shared data 129. When the permission analysis module 124 determines that the access of the shared data 129 has not yet exceeded the number of times or period of time for accessing the data 129, it will grant the access operation of the shared data 129. Consequently, the permission control module 126 is allowed to access the shared data 129. In certain embodiments in Step S508, the receiving device 12 contains a predefined permission (second permission), determine the final permission to be used according to the permission configured by the sharing device 10 and the local predefined permission, and access the data 129 based on the final permission. The data management method 5 is completed and exited (S512).
The embodiments in
The data management method 7 will be performed after the touch link electronic devices 60 and 62 determine to share data with one another (S700). Firstly, the touch link electronic devices 60 and 62 can configure the permission of the shared data according to the type of the other device, type of the shared data, or user preference (S702). Next, the touch link electronic devices 60 and 62 can establish the touch connection L1 via a touch in close proximity (S704). Subsequent Steps S706, S708, S710 and S718 may be operated concurrently and parallel to the Steps S712, S714, S716 and S720, respectively.
To begin with, the touch link electronic devices 60 and 62 can deliver the permission for sharing data to each other via the touch connection L1 (S706, S712). In response, the touch link electronic devices 62 and 60 can receive the permission from each other via the touch connection L1 (S708, S714). Later, the touch link electronic devices 62 and 60 can share the data to each other (S710, S716). Correspondingly, the touch link electronic devices 62 and 60 can receive the shared data from each other via the touch connection L1 (S718, S720). The data management method 7 is then completed and exits.
The data management method 9 will be performed after the sharing device 80 determines to share data to the receiving devices 82 and 84 (S900). Firstly, since the sharing device 80 determines wishes to share the data 806a and 806b with the receiving devices 82 and 84, respectively, the permissions 802a and 802b corresponding to the data 806a and 806b are configured, respectively (S902). It follows that the receiving devices 82 and 84 can concurrently or sequentially touch the sharing device 80 to establish the touch connections L1 and L3.
Subsequent Steps S906, S908, S910 and S918 may be operated concurrently and parallel to the Steps S912, S914, S916 and S920, respectively. To begin with, the sharing device 80 can transmit the permission 802a and 802b to the receiving devices 82 and 84 via the touch connections L1 and L3, respectively (S906, S912). In response, the receiving devices 82 and 84 can respectively receive the permission 802a and 802b from the sharing device 80 via the touch connections L1 and L3 (S908, S914). Later, the receiving devices 82 and 84 may concurrently or separately establish the wireless connections L2 and L4 to the sharing device 80, and the sharing device 80 can share the data with the receiving devices 82 and 84 via the wireless connections L2 and L4 (S910, S916). Correspondingly, the receiving devices 82 and 84 can respectively receive the shared data from the sharing device 80 via the wireless connections L2 and L4 (S918, S920). The data management method 9 is then completed and exits.
